90 mins at 400km vs 110 mins at 1400km
- jbrot 6y agoI guess that makes sense since the Earth’s radius is around 6400km so from 400 to 1400km is really a change from 6800 to 7800km which is proportionally similar to a change from 90 to 110 minutes. Edit: I just looked up the formula for orbital period and it turns out period is proportional to radius^(3/2) (See: https://en.m.wikipedia.org/wiki/Orbital_period https://en.m.wikipedia.org/wiki/Orbital_period)
